Description
Hi everyone,I built a small web tool called Datamorph because I kept running into JSON/CSV converters that either broke with nested data, required login, or added weird formatting.Datamorph is a minimal, fast, no-login tool that can:• Convert JSON → CSV and CSV → JSON • Auto-detect structure (arrays, nested objects, mixed data) • Handle uploads or manual text input • Beautify / fix invalid JSON • Give clean, flat CSV output for real-world messy dataIt’s built with React + Supabase + serverless functions. Everything runs client-side except file parsing, so nothing is stored.I know there are many similar tools, but I tried focusing on:• better handling of nested JSON, • simpler UI, • zero ads / zero login, • instant conversion without waiting.Would love feedback on edge cases it fails on, or features you think would make this actually useful for devs and analysts.Live tool: https://datamorphio.vercel.app/Thanks for checking it out!

Could you build this?
Yes A client-side JSON to CSV (and vice versa) converter tool with schema auto-detection is easily vibe-coded using standard browser JavaScript and existing parsing libraries.
